5 simple tips to reduce electrosmog at home

The router and wireless devices such as the cell phone, cordless phone or Bluetooth speaker generate electromagnetic fields (EMF). It is becoming increasingly difficult to escape this radiation. WLAN is now even available in supermarkets. So it can’t hurt to keep electrosmog as low as possible, at least within your own four walls.

Although science has been unable to establish a link between symptoms of illness and electromagnetic fields (EMF) over the past 30 years, according to the Federal Office for Radiation Protection, between one and two percent of Germans describe themselves as electrosensitive. Electromagnetic hypersensitivity, however, is not classified as a disease either in Germany or by the World Health Organization (WHO).

More and more devices that generate EMF

However, it has been proven that humans can perceive electric and electromagnetic fields, after all, we are constantly surrounded by them – including fields that are of natural origin such as the earth’s magnetic field or electric fields that we generate ourselves. The following applies to all artificially generated EMFs: the lower the impact on the body, the better – even if there are limits for such fields that rule out any damage to health.

Electromagnetic fields abound in the apartment or house. In addition to devices that require electricity to operate, this also includes all devices that are connected to the WLAN or wirelessly in some other way. (e.g., via Bluetooth, DECT or LTE). And there are more and more of them: cordless phones are now joined by TVs, vacuum robots, Bluetooth speakers, baby monitors, remote-controlled shutters, smart heating systems, etc.

1.) Turn off devices when not in use

Clearly, devices that don’t transmit and don’t draw power don’t radiate. So consider simply turning off some devices that aren’t needed in certain situations. Example: At night, you can activate airplane mode on your smartphone. Functions such as the alarm clock or audio playback for a downloaded audiobook, for example, will still work.

In order to reduce the electrosmog from current-operated devices, you can use mains isolation switches, as known from socket strips. The mains isolation switch is installed in the fuse box by an electrician. The switch disconnects the mains voltage for entire rooms. As soon as an appliance is activated in one of the disconnected rooms, power automatically flows again.

The only problem with the mains isolation switch is that it does not work with devices that are in standby mode or that require permanent power. This means that the mains isolation switch does not work in the room where the WLAN router is connected to the mains.

2.) Reduce transmitting power

Instead, you can reduce WLAN radiation in other ways. Instead of letting the router transmit around the clock, you can deactivate the WLAN on most devices for a freely selectable period, for example between midnight and six in the morning. The router then automatically switches the WLAN off and on again.

Many routers also offer the function to reduce the transmission power. This allows you to concentrate the WLAN signal in certain rooms and leave out the bedroom, for example.

3.) Smartphones, signal strength and cabling

However, a minimum signal strength is not always an advantage. If cell phone reception is poor, for example, the smartphone has to increase its transmission power. Therefore, only make mobile calls when there is a sufficiently strong network.

As a general rule, cabling causes less electromagnetic radiation than radio transmission. The PC in the home office should therefore ideally be connected to the router via LAN or Powerline (Internet via the power cabling). When looking at the cables, take a look at the shielding: the better the shielding, the less electrosmog.

4.) Beware of the DECT standard

Of course, you can’t do without wireless. When buying a cordless phone or a baby monitor, for example, make sure you know how signals are transmitted wirelessly and whether you can reduce the transmission power.

The DECT standard, which is mainly used for cordless phones, usually has a higher transmission power than a smartphone. The base station of a DECT phone should therefore only transmit when you are actually on the phone. Look for a baby monitor that does not transmit signals continuously using DECT. It also can’t hurt if the baby monitor is certified with the “Blue Angel”.

5.) Keep distance

The further away the source of an electromagnetic field, the lower its radiation. A baby monitor should be placed about one to two meters away from the bed. Use a headset when making calls with your smartphone – one with a cable, of course, otherwise you’ll have an additional EMF near your body with Bluetooth transmission between the headset and smartphone.
